We have recently demonstrated new 2 V PJVS devices configured with two voltage outputs and two sets of least significant bits in order to simultaneously generate two independent stepwise output waveforms. This development improves upon our previous a

29th Conference on Precision Electromagnetic Measurements (CPEM 2014).
A voltage amplifier composed of three cascaded −10:1 gain sections has been developed to extend the voltage range of primary electric power calibrations from 120 to 600 V over the 50–400-Hz frequency range. The gain and phase errors of each ampli
